Tropical Storm Howard Discussion Number  16

Deep convection in the northern semicircle has continued to slowly 
decrease in depth and coverage while Howard moves over cooler 
waters.  As a result, the objective and subjective satellite 
intensity estimates have reduced and the initial intensity estimate 
has been lower to 55 kt.  Steady weakening is expected to continue 
as the cyclone approaches sea surface temperatures cooler than 24 
degrees C and moves into an increasingly dry and stable environment. 
These oceanic and atmospheric factors should cause Howard to 
degenerate into a remnant low in about a day and a half.  The 
official forecast is similar to the previous advisory and now shows 
Howard becoming a post-tropical cyclone in 24 hours.

The tropical storm is moving northwestward at about 9 kt around a 
subtropical ridge.  Howard is expected to turn west-northwestward 
later today followed by westward on Thursday when the weaker, more 
shallow vortex is steered by the low-level flow.  The NHC track 
forecast is very similar to the previous official prediction and 
close to model consensus guidance.
